NCT02946983

Brief Summary

The investigators will test whether a subliminal, intragastric dose of fructose is able to influence the emotional state at the behavioural and neural level, as has been previously shown for fatty acids. They will also examine the potential involvement of gut peptide release. Based on previous research using fatty acids, an attenuating effect of fructose compared to placebo on the induced negative emotional state is hypothesized at the self-report as well as the brain level.

Outcome Measures

Primary Outcomes (1)

  • Functional brain images

    Changes in brain responses after administration of our test solution compared to baseline will be assessed via functional magnetic resonance imaging

    From the start of the study until the endpoint of the study, with a total duration of 50 minutes

Secondary Outcomes (3)

  • Hunger scores

    every 10 minutes since the scan starts until 40 minutes after the start of the scan

  • Mood assessment via the Self Assessment Manikin questionnaire

    every 10 minutes since the scan starts until 40 minutes after the start of the scan

  • Gut hormone levels

    every 10 minutes since the scan starts until 40 minutes after the start of the scan
